Program not running (Overloading problem)

[anurag123]

class Area(object):
    def get_area(self):
        return("WORKING FINE")
class Rectangle(Area):
    def get_area(self,l,b):
        self.l=l
        self.b=b
        return (self.l*self.b)
class Circle(Rectangle):
    def get_area(self,r):
        self.r=r
        return (3.14*self.r*self.r)
obj=Circle()
print(obj.get_area())
print(obj.get_area(6,3))

obj.get_area requires an argument, r, and only one
so format would be obj.get_area(10) for example

I don't know why you call it overloading, as you are not overloading anything.
You only overload a class when yo are going to change the operation of one or more of the methods,
and that is done thusly:

import myclass

class circle(myclass):

Unrelated, but why is Circle extending Rectangle? They're very different, unrelated things, and anything that they might happen to share would be in the base Area class.
